TOBACCO-PIPE.

Specification of Letters Patent.

Patented Aug. 25, 1914..

Application filed July 13, 1911. Serial No. 638,249.

To all 'whom it may concern:

Be it known that I. Fnnonnron. H. A. MOEHLENBROCK, a citizen of the United States of America, residin in the city of St. Louis and State of Missouri, have invented certain new and useful Improve: ments in Tobacco-Pipes, of which the following is a specification.

This invention relates to pipes, and has for its primary object to provide an improved construction, combination and arrangement of parts in a device of this character.

One of the objects of the present invention is to provide an improved bowlconstruction, whereby the bowl can be continuously cooled by means of a current of airpassing around the same throughout practically its entire outer surface.

Another object is to provide improved means for separatingthe nicotin and liquids from the smoke at diiferent points along the smoke conveying passageway.

A further object is to provide animproved removable nicotin and moisture collector.

Another object is to provide an improved stem construction.

Other and further objects willappear in the specification and be specifically pointed out in theappended claims, reference being had to the accompanying drawings exemplifying the invention, and in which,

Figure 1 is a side elevation of a pipe constructed in accordance with the principles of the present invention. Fig. 2 is .a vertical section of the same, with the stem shown in elevation. Fig. 3 is a fragmentary sectional view of the same howing the stem construction. Fig. 4 is a section on the line IV-IV, Fig. 1. Fig. 5 is a section on the line V-V, Fig. 3. Fig. 6 is a section on the line VI'VI, Fig. 2. Fig. 7 is a fragmentary side elevation of a modified form of the pipe,

artly broken away, and parts being shown in section.

Referrin more particularly to the drawings, and rst to the embodiment shown in Figs. 1 to 6, inclusive, the pipe comprises a base member 1 provided with a stem receiving socket 2 for receiving a stem 3, a removable bowl 4, a ventilating'shell 5 surrounding the bowl .4, and a removable receptacle 6 for nicotin and moisture.

The base member 1 is provided above with a concave seat or socket l of greater curvature than the curved bottom of the bowl 4,

thereby providing an air space extending beneath a portion of the bottom of the bowl 4 for cooling purposes. As shown in Fig. 2, the upper interior wall of the bowl 4 is recessed .to receive the downwardly deflected flange 8 of the cooling shell 5. said shell being deflected toward the. top and extending over the upper edge of the bowl 4, so that it is adapted to support said bowl at .the top. The shell 5 is spaced from the bowl 4 to provide an air space 9, the construction already described making it possibleto construct the bowl4 relatively thin.

Within the lower cylindrical. portion of the shell 5 are provided a plurality of air inlet openings 10 which are preferably arranged inseries horizontally Above these openings, .andpreferably .in the upper inclined portion of the shell, are outlet openings 11. The shell 5 is mounted upon the base 1 by means of it lower edge which grips the annular shoulder 12. Opening from the bottom face of the base member 1, is a recess for receiving the receptacle 6, said receptacle comprising a downwardly open. shell 13 provided with a serrated flange 14 at either end to adapt it to be pressed into the recess, the serration serving to retain it in position after it has been thrust home. In order to provide a removable cover for the receptacle, an outer shell 15 fits over the curved wall ofthe inner shell 13, projecting intothe annular space left between the inner shell and the curved wall of the recess.

In order-to provide suitable means for releasably connecting thebase member 1,.the bowl 4, and receptacle 6, a hollow stud 16 is employed, whose head engages the top wall of the inner shell 13, and whose extremity is threaded to the bowl 4. A tubular assageway 17 in the stud 16 conveys the smoliefrom the bowl into the receptacle 6. By having the passageway 17 opening through the head of the stud 16, the inner wall of the receptacle 6 is made lrregular, so that any fluid nicotin does not dram into a position to be sucked in by the smoker. In order, however, to accentuate thls feature, the top wall of theinner shell 13 1s stamped downwardly into the form shown at 18 in Figs. 2 and 6. This depending portion 18 is provided below with an inlet opening 19, and enlarged upwardly so that the vertically inclined smoke passage 20 can be made of smaller diameter than the upper end of the portion 18. The passage 20 discharges into an annular chamber 21 which is formed between the inner cylindrical wall of the stem socket 2 and a stopper 22 for the lower end of the stem chamber 23 formed within the stem portion 24. The outer cylindrical wall of the stem portion 24 is provided with a. helical groove 25 which opens at its lower end into the annular chamber 21, and at its upper end communicates through a radial aperture 26 with'the upper end of the chamber 23.

As shown best in Fig. 3, the mouth piece of the stem is divided from the portion 24, being secured thereto by means of a threaded tube 27 which forms a portion of the smoke duct 28 and depends for some distance into the chamber 23. As shown in Fig. 6, the head of the stud 16 is provided with a slot 29 by means of which it may be screwed into and out of position.

In the modification shown in Fig. 7 the base member 1 is extended much higher than in the former embodiment, its cylindrical wall being provided with a plurality of vertically elongated openings 31, through which the air may pass freely into the annular chamber surrounding the bowl 4:. In this embodiment, the metallic housing 5 is of comparatively small extent, being seated on the upper end of the base member 1. As

shown in Figs. 1 and 7, the base members are notched at 30 to enable the finger and thumb to beinserted into engagement with the flange on the bottom of the nicotin and moisture receptacle.

The advantages of my improved construction will now be appreciated, and briefly stated are as follows: The bowl, nicotin receptacle, and stem are all removable and have their cavities and passageways readily accessible for cleaning purposes. The bOWl construction enables "the bowl 4 to be very economically constructed and readily cooled. The stem portion 24 by having a helical smoke passage 25 on its outerv surface is very easily cleaned, and moreover connects with. the annular chamber 21 away from the points at which the channel 20 connects therewith. A further feature of improvement isthe chamber 23 within which any moisture or nicotin which reaches the port 25 is intercepted, and into which the saliva from the smoke duct 27 discharges. The member 22 and the removable connection 26 give very ready access to'the chamber 23 for cleaning purposes.

It is desired to lay stress upon the fact that while I prefer to provide a helical groove in the depending stem portion. said portion might, within the spirit of my in- I l vention, be provlded wlth a groove running in any direction around the outer wall, or

with a passageway extending through and contained entirely within the wall of the depending portion.
